I treat with tylosin in the form of Tylan-50 found in your local feed store dosed at 20-30 mg/lb intramuscularly daily for 5-7 days or you can give the injectable solution orally directly into your hen's beak. Please note that appropriate antibiotics such as tylosin may be effective in alleviating signs of disease but don't affect the carrier status. In other words, a hen is likely to remain a carrier of Haemophilus paragallinarum (chicken coryza) indefinitely. This is a common organism in poultry flocks. The infection is passed from age group to age group as replacement stock is introduced to the farm.
